GAS MIXER.

Application filed March 30, 1921. Serial No. 456,791.

To all whom it may concern:

Be it known that I, HERBERT RAYMO-ND GREEN, a citizen of the UnitedStates, residing at New Britain, in the county of Hartford and State ofConnecticut, have lnvented certain new and useful Improvements in GasMixers, of which the following is a specification.

My invention relates to improvements in gas mixers of the form that isused for 11nproving the mixing of the fuel and the an intermediate thecarbureter and the intake manifold of an internal combustion engine, andthe object of my improvement is to produce a device that can beinterposed between the flanges on the carbureter and manifold that serveto inter-connect these parts; that is in the form of a unitary piece ofsheet material that bridges the opening or passageway for the fuel andair mixture; that has a plurality of openings so as to serve tosubdivide the said passageway into a corresponding number of individualfuel openings; the wall portion of each of which individual openingshaving one or more deflecting devices in the form of vanes for divertingthe fuel and air stream to one side of the axis of the passageway; and,furthermore, which deflecting devices are constructed and arranged in aspecial manner for effecting a superior result as to such mixing,consistent with simplicity in construction.

In the accompanying drawin Figure 1 is a side elevation 0 part of theconnection for an internal-combustion engine with the opposed flangesfor connecting the carbureter to the intake manifold, and having myimproved gas mixer interposed between the said flanges.

Figure 2 is a side elevation on an enlarged scale of the gas mixer.

Figure 3 is a front elevation of the same,

Figure 4 is a rear elevation of the same.

Figure 5 is a fragmentary front elevation of a portion of the gas mixer,on a still further enlarged scale, showing the details of the deflectingvanes, p

My improved gas mixer comprises a unitary structure 10 having a borderportlon 11 of suitable size and shape to be interposed between theopposed flanges 12 of the carbureter 13 and the intake manifold 14 of aninternal-combustion engine; has openings 15 in the form of slots foradmitting the-'.

bolts 16 that hold the parts in place; is made of sheet metal ofappreciable thickness; and has the middle portion, designated enerallyby the character 17 subdivided in a spec al manner so as to provide aplurallty of individual fuel openings 18, which middle portion 17 servesgenerally to bridge the passageway leading from the carbureter 13 to theintake manifold 14:; and, furthermore, each fuel opening 18, as shown,is provlded with a pair of'vanes or deflectors, comprising in each casean outer vane 20 and an inner vane 21.

The two vanes of each pair are directed towards opposite sides of thelongitudinal directlon of the passageway 19, and each is bent to anappreciable angle, and, furthermore each is of appreciable size, so asto be adapted to serve as a baflie or deflecting device for deflectingthe stream of the fuel mixture to one side of the general longitudinaldirection.

As a structural detail, the entire material of the blank to correspondto the size of the passageway 19 is utilized for forming the vanes 20and 21, except such as. is found necessary to provide a suitable supportmechanically for the 'vanes.

The mechanical structure may be briefly described as comprising aplurality of ra- -dially directed spokes 22 that meet at the middle at ahub 23 and merge at the outer ends 24 with the material of the borderportion 11. The material intermediate adjacent spokes 22 is utilized for.forming the vanes, the part of such material adjacent the hub 23 beingdeflected to one side to form the inner vanes 20 and the part thereofadjacent the border structure 11 being deflected in the oppositedirection;

As shown, there are six spokes 22 and a corresponding number of vanes.

All of the outer vanes 20 are deflected in the same direction, so thatthey are adapted to cooperate to provide alateral direction to the fuelmixture in its passage through the 1 gas mixer sofar as applies to whatmay be designated as the outer zone of the general fuel passageway, theeffect being briefly described as a whirling eflect.

Similarly the inner vanes 21 produce a whirling effect on the fuel forthe ortion that travels along what may""-be des1gnated as the innerzone, adjacent the longitudinal. axis of the passageway 19. i The fuelwould accordingly comprise an inner core portion that is whirling in onedirection and that is surrounded by a skin,

portion or border Wall portion that is whirling in the oppositedirection.

As these two portions move along the intake manifold they mingle andthereby serve to more thoroughly mix the fuel and the air so as toenhance the eficiency of the coinbustion.

I claim as my invention A gas mixer in the form of a single piece ofsheet material having a general main opening that is enclosed by aborder Wall naeeoee of circular form, a plurality of spoke structuresextending radially inwardly from said border wall and meeting at themiddle of said opening, a setof vanes supported by the outer portions ofsaid spoke structures and a second set of vanes supported by the ierportions of said spoke structures, and the two sets of vanes beingdeflected in opposite directions relatively to the line of the axis of20 said opening. 1
